Siemens HLXD63B600 Molded Case Circuit Breaker – Sentron Series – 600A – 3 Pole – 600V – Bolt-On – Thermal Magnetic – High Interrupting Capacity

The Siemens HLXD63B600 is a Sentron Series molded case circuit breaker designed for heavy-duty industrial and commercial power distribution systems. Rated at 600A and 600V AC, this 3-pole breaker provides reliable circuit protection using a thermal-magnetic trip unit with long-time overload and instantaneous short-circuit protection for safe and stable operation under demanding electrical conditions.

Built for high fault current environments, the HLXD63B600 delivers a high interrupting capacity of 65kA at 480V. Its bolt-on mounting design, compact Sentron HLXD frame construction, and non-interchangeable trip unit ensure durability, safety, and consistent performance in critical power distribution applications.
